Line 3 Replacement Project (U.S.)

Life takes energy—to heat our homes, to feed our families, to fuel our vehicles. Enbridge has been proudly fueling Minnesota's quality of life for 65 years.

The Line 3 Replacement Program, the largest project in Enbridge history, represents an improvement of our pipeline infrastructure—helping to ensure that Minnesota and the surrounding region are connected to secure, reliable and growing supplies of North American crude oil.

The $2.9-billion U.S. portion of the Line 3 Replacement Program, known as the Line 3 Replacement Project, consists of replacing existing 34-inch pipe with new 36-inch pipe for 13 miles in North Dakota, 337 miles in Minnesota, and 14 miles in Wisconsin.

On June 28, 2018, the Minnesota Public Utilities Commission (PUC) approved the Line 3 Replacement Project, granting a Certificate of Need and approving Enbridge’s preferred route with minor modifications and certain conditions. Construction is expected to begin early in 2019 in Minnesota, and Enbridge continues to anticipate an in-service date in the second half of 2019.

Enbridge’s private investment—$2.6 billion of it in Minnesota—will create well-paying jobs, an economic boost for local communities during construction, and local community investments and tax contributions for many years to come.
